Question

An elevator is accelerating down at 2 m/s in which a simple pendulum is suspended on
one of its vertical wall with string length 2m. The string is pulled aside and bob is held
horizontally with string tight. The minimum downward speed (in m/s) with which bob
is to be thrown so that bob completes the vertical circle is given by 4 k. Then value of
k is :​

Answer 1

Answer:

The motion of a pendulum is a classic example of mechanical energy conservation. A pendulum consists of a mass (known as a bob) attached by a string to a pivot point. ... However, the force of tension does not do work since it always acts in a direction perpendicular to the motion of the bob.
